I HENRY M. VEAVER, OF MANSFIELD, OHIO.

GRATE.

SPECIFICATION forming part of Letters Patent No. 347,401, dated August17, 1886.

Application filed November 12, 1885. Serial No. 182,582. (No model.)

To all whom it may concern:

Be it known that I, HENRY M. \VEAVER, of 'Mansfield, in the county ofRichland and State of Ohio, have invented certain new and usefulImprovements in Grates; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in grates.

The object is to .provide a grate by which the ashes and cinders may beeffectually and conveniently removed from the fire-pot either while thefire is burning or after it is out.

A further object is to provide an apron adapted to prevent the ashesfrom falling onto the hearth in front of the grate, and to form a neatfinish in front, and which shall be capa ble of being tilted to admit ofcleaning the hearth, dumping the grate, &c.

A further object is to provide an improved construction of the portionof the front and back situated in close proximity to the gratebars,whereby the slicing and crushing of the cinders and removal of the ashesmay be more effectually aecomplished,and to provide improved means forconnecting the grate-bars with the operating-rod.

. With these ends in view my invention 0011- sists in certain featuresof construction and combinations of parts, as will be hereinafterdescribed, and'pointed out in the claims.

In the accompanying drawings, Figure 1 is a View of the grate inperspective, showing the apron tilted. Fig. 2 is a view in vertical 4transverse section, on the line a: xof Fig. l,

showing the apron in its normal position; and Fig. 3 is averticaltransverse section on the line y y of Fig. 1, showing the apron tilted.

A represents a supporting-frame resting on legs a. The frame isconveniently oblong in shape, but may have other shapes, as desired. Thefront consists of a pair of end uprights, B, resting on a plane with thelower ends of the legs a, and connected by an upper anda lower rail, 1)and 1), between which the series of upright bars 0 extend. The railsbbcurve backwardly as they leave the uprights B, the lower rail, 1),resting on the front of the supporting-frame A.

The supporting-frame A is, provided near its ends with cross-bars D,which are connected with the end bars by guide'cheeks d, arranged inpairs for holding the longitudinallysliding grate-bars in position. Thecross-bars D are provided with one or more sets of upwardly-extendinglugs, E, between which the rounded bearings 011 the rocking grate bar orbars loosely fit.

F represents one of the rocking grate-bars, and G represents one of thelongitudinallyreciprocating bars. The grate shown in the accompanyingdrawings consists of three independent bars-one rocking and twolongitudinally reciprocating, the rocking bar being located between thetwo reciprocating bars. This number and position of the bars is nothowever, essential, as there might be two or more rocking bars and one,or more than two reciprocating bars, and the rocking bars might bearranged alternately with the reciprocating bars, or the rocking barsand the reciprocating bars might either or both be arranged in groups oftwo or more.

The bars as presented in the drawings are all of the same general type,consisting of a main trunk provided on each side withlaterally-extending branches, the upper face or edge of the trunk, andthe upper faces of the branches being slightly hollowed out, as shown.

The rounded parts or journals f of the rockbar are located between theend branches and the branches next thereto, the bar being held by thesaid branches against longitudinal displacement. The ends of the bars Grare squared, as shown at g, to fitloosely between the cheeks d, thelongitudinally sliding motion of the bar being limited by theupwardly-extending flanges H on the ends of the frameA.

The bar or bars F are rocked by means of a combined latch andoperating-rod I, one end of which is pivotally secured to the lower endof a depending. lug, h, formed on the bar F, and the other end of whichextends toward the front through an elongated. closed slot, k. formed ina depending lug, H, attached to the front of the frame A. The under edgeof the latch I is provided with a notch, z, adapted to receive the edgeof the lug H at the bottom of the slot k, and thereby lock the bar F inadjustment for use. If more than one rock-bar is employed,they may beconnected and rocked by the latch I in the same manner as the bar F isrocked.

Arock-shaft or operating-rod, L, is journaled transversely to thegrate-bars in suitable bear ings formed in the front and back of theframe A, and is preferably located at the opposite end of the grate-barsfrom the latch I. The rod or shaft L is provided, directly beneath thebar or bars G, with a loop-shaped lug or lugs, Z, adapted to engage aslot or recess, M, formed between a pair of depending lugs, m, on theunder side of the bar. The open space in the loop-shaped lug Z allowsthe ends of the lugs m to enter therein as the bar G is movedlongitudinally, thereby affording a more positive hold than is obtainedby the ordinary lug and recess. The rod or shaft L is also convenientlycranked at the points where the lugs Z are formed, to give the bar Galonger stroke without increasing the length of the lug Z.

The upright bars G are provided on their inside faces, at pointsopposite the ends of the branches on the bar G, with inwardly-extendingin gs N, the upper sides of which are formed slanting from the bars 0toward the grate-bar, thereby tending to crowd the ashes and cindersaway from the front bars, 0, onto the grate, and forming, in conjunctionwith the projection a of the bar G, an effective device for crushing andloosening the ashes and cinders. A bar, 0, provided with a set of lugs,0, corresponding to the branches on the gratebar, is adapted to besecured to the supporting-frame A at the back of the grate and in closeproximity to the grate-bar.

The front of the grate is provided with an apron, I, which is removablysecured to the uprights B by means of a pair of depending hooks, p,secured to the inside face of the apron at its ends, said hooks beingadapted to engage laterallyextending lugs q on the uprights. The hooksare so located on the apron that when in engagement with thelngs q theapron will automatically retain ahorizontal position. The apron islocked in vertical adjustment by means of a pair of lugs, It, at thelower ends of the uprights B, which prevent the bottom of the apron fromswinging inwardly accidentally. To tilt the apron,the latter is raiseduntil the lower edge of same clears the top of the lugs It. Then,byreleasing the apron and, if necessary, pulling outwardly on the upperend thereof, the latter will turn to the position shown in Fig. 3. Toturn the apron to an upright position,the outer or upper end of same ismoved toward the grate, during which movement the lower edge thereofrides up and passes the inclines It. The top v'of the apron is made torecedc from the bars 0, thereby forming a guard to prevent the ashes andcoals which might work through between the bars 0 from falling on thehearth in front of the grate and guiding the same beneath the grate intothe aslrreceptacle.

The apron when vertically adjusted forms a neat finish to the front andhides the ashreceptacle, latch, and rock-shaft, the rockshaftterminating inside of' the apron. \Vhen in a horizontal adjustment, thehearth may be cleaned and the latch operated. The rockshaft may beoperated when the apron is in either vertical or horizontal adjustmentby means of a lever inserted in a socket, .9, formed in its head. By notallowing the rockshaft to extend through the apron the latter may bemore readily removed and manufactured at less expense.

\Vhen the grate is composed of aeentral rock-bar and two outsidereciprocating bars, as shown in the drawings, the ashes may be shakeninto the receptacle by the rocking of the shaft L, which reciprocatesthe bars G, and the cinders may be removed by rocking the grate-bar F.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myselfstrictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a grate, the combination, with a supporting-frame, of two or moreparallel independent grate -bars located thereon, one or more of saidbars being pivoted to the frame, whereby it (or they) can be rocked, andthe ends of one or more of the bars resting on bearings constructed topermit the said bar or bars to haveasliding movement in said frame,substantially as set forth.

2. In a grate, the combination, with a supporting-frame, of two or moreindependent grate bars located in the same horizontal plane, one or moreof said bars being pivoted to the frame, and one or more of the barsresting loosely in bearings, whereby it (or they) may have alongitudinal sliding movement on said frame, substantially as set forth.

3. In a grate, the combination, withagratcframe, of parallel bars, oneof which is pivoted to the grate-frame, and the adjacent bar restingloosely in bearings, whereby it may have a sliding movement on saidframe, substantially as set forth.

4. The combination with a rocking grate and its supporting-frame, of anapron pivoted to the frame below the front edge of the grate, thepivotal point being above the lower edge of the apron, as set forth.

5. In a grate, the combination, with a sup porting-frame and areciprocating grate-bar having a recess in the lower side, the saidframe having side cheeks and flanges forholding the bar laterallyagainst displacement, and for limiting the longitudinal movement of saidbar, of a rocleshaft, and a loop-shaped lug secured to said shaft andresting within said recess in the bottom of the reciprocating bar,substantially as set forth.

6. In a grate, the combination,with a frame,

one or more reciprocating grate-bars, and one or more rockinggrate-bars, the said bars beporting-fran1e, of a tilting apron securedto,

the front of the grate and provided with an outwardly-flaring upperedge, substantially as set forth.

9. The combination, with a frame having upper and lower lugs,substantially as described, and a grate supported on said frame, of anapron having hooks projecting from the rear face of the apron andengaging the upper lugs, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
